Fatentecl June 17, 1930 i l CHRISTIAN J. HUG, OF HIGHLAND, ILLINOIS-TRUCK BODY Application filed June'G, 1929. Serial No. 368,760.

My invention relates to improvements in means ofstub-shafts 22-22 to thestandards truck bodies and has for its particular object 23-23 which aremounted at the outer termito provide a truck body especially adaptednals of one of the transverse beams 14. At to the hauling and dumping ofviscous matetheir rear ends, the lever-arms D-D are 5 rials. pivoted tolinks 24-24: by means ofpins 5 The body of my invention is arranged to25-25; the links 24-24 in turn being pivotreceive its load at its opentop and to disally attached to plates 26-26, which plates charge thesame through a series of succes- 26-26 are mounted upon the side Wallsof sively-opening trap doors forming its botthe truck body A as shown.The bottom of tom; and the charge thus unloaded through the truck body Ais contoured as shown to fit 5?, the bottom being caught in a troughwhich within the upturned outer flanges of the serves to hold the bodywhen said body is trough C, the front end of the truck body A beingloaded or carried and which is tilted having sliding contact with thetrough C by to form a delivery chute during the process means of theguide 28. The bottom of the of unloading. I body A consists of aseriesof trap doors F, co Other incidents of my invention, will be eachhingedly mounted by means of a transapparent from the followingdescription. verse pintle 30, each hinge so formed being located withina housing 31, triangular in transverse section as shown, said housing 31Fig. 1 is a side elevation ofa truck body serving to, keep the viscouscontent of the 65- embodying my invention, in position for body A inpartially divided batches Within loading and carrying. said body A.' Thetrap doors F are kept Fig. 2 is a like view of the same in unloadclosedby contact with the bottom of the Drawings ing position. trough C whenthe body A is in loading or v Fig. 3 is a rear elevation of the same.carrying position as shown in Figs. 1 and3. 70

Description The links 24-24 are each made extensible by means of aturnbuckle T thus adjusting A shown in the drawings, the body A is thelength of the link 24 to control the length carried by the chassis frame13, the'fra-me B of upward throw of the rear end of the comprising sidesills 10-10 braced by transbody A. v

The trough C is supported by a tilfition (namely,that illustrated in Figs. 1 and ing frame E, composed of thelongitudinal 3), the lever mechanism which includes the I-bearns 13-13and cross beams 14, the beams lever-arm D serves to hold the body A,chassis l313 being P y attached to the r frame B and'trough C securelytogether. 8

end of the chassis B by means of the brackets In the handling of certain.materialsof the 15-15 and pins 16-16. class for whose transportationthe truck body Bearing braces 17 are secured to the outer of myinvention is intended, there will at ends of the brackets 12-12 by bolts18 and times during transportation, and before arthe lower terminals ofthe lever-arms 19-19 rival at the place of discharge of the load, aresecured to said plates 17-17 by said bolts be a settling of the heaviermaterial to the I 18. At their upper ends the lever-arms bottom with theresult of leaving a relatively 19-19 are pivotally connected by means ofliquid mass at the top of the load. In order pins 21-21 with the forwardterminals of to prevent the rearward slopping of such liq- 4 thelever-arms D-D which are mounted by uid' matter during the operation ofdischarge,

of which is pivoted the rod 42 extending rearwardly through a slot 43'in a plate 44-,which plates 44 are mounted at the lower outer corners ofthe tail-gate 45, which tail-gate 45 closes the rear end of the body A.-

To the frame E the lifting cord 46 is subjected to an upward pull by anydesired and appropriate mechanism (not shown) to tilt the body A to theposition shown in Fig. 2 and discharge its contents.

Mode of operation The body A having been loaded andtransported tot-hedesired point of deposit, the cord 46 is pulled upwardly to tilt thebody A from the position illustrated in Fig. 1 to the positionillustrated in Fig. 2. During this operation the body A and trough G areforced to gradually diverge, and the trap doors E are successivelyopened from the rear to the front of the body r-Lso that the last of theseries of trap doors E, hinged at the front end of the body A, will haveits lower edge in contact with the bottom of the trough C, as shown inFig. 2. During this operation the body A gradually assumes a tiltedpositiomas shown in Fig. 2.

The load being dumped, the pull on the cord 46 is released, permittingthe parts to resume their contact and locked relationship illustrated inFig. 1. The lower edges. of the-trap doors E are preferably slightlyturned rearwardly as indicated by 4L7 to facilitate their re-seating inplace within the bottom of the trough C.

f Many variations of structure may be'made without departure from myactual invention as defined by the appended claims.

Claims:

1. A device of the class described comprisinga truck body; a bottom forsaid body composed of a series of trap doors; a trough wherein said bodynormally rests; a chassis frame whereon said trough is hingedly mounted;and means for elevating the forward end of said trough to discharge thecontents ofsaid body; in combination with a lever mechanism arranged tocontrol the relative positions of said body, trough and chassis framewhen in loading position, and when unloading. v

2. A device of the class described comprising a truck body; bottom forsaid body composed of a series of trap doors; a trough wherein said bodynormally rests; a chassis frame whereon said trough is hingedly mounted;and means for elevating the forward end of said trough to discharge thecontents of said body; in combination with Y cluding an extensible linkto vary the throw of the body when unloading.

In testimony whereof I have hereunto a ffixed my signature.
